Arkon OCTO™ Ratcheting Arm with 18" Heavy-Duty Seat Rail Mount with AMPS Mounting Pattern

The OCTO™ Ratcheting Arm with 18" Heavy-Duty Seat Rail Mount provides a strong, fully adjustable solution for securely positioning your phone or tablet in cars, trucks, and fleet vehicles. The 18-inch aluminum gooseneck bends easily into place while maintaining a firm hold, and the mount installs directly to your vehicle’s seat rail using the passenger seat bolt—no drilling required. A drill-base option is also included for permanent mounting setups.

At the top of the gooseneck, the OCTO™ Ratcheting Arm delivers smooth, controlled adjustability with 360-degree rotation and multiple pivot points, making it easy to set the perfect viewing angle for navigation, ELD apps, or in-cab workflows. Built from reinforced materials for daily use on the road, this mount is compatible with all 4-hole AMPS holders, cradles, and adapters.
